LINE-WIRE FASTE NER.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed August 1, 1907. Serial No. 386,537.

To all whom it may concern:

Be it known that I, LAFAYETTE STANTON, a citizen of the United States, residing at Beaver River, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Line-Wire Fasteners, of which the following is a speci fication. 7

My invention relates to improvements in fasteners or clamps especially for applying telegraph, telephone or other line wires to their insulators as in suspending the same in position from poles or other supports. Its objects are mainly to obviate winding pieces of wire around the line-wire after passmg the same around the insulator, as in fastening or connecting the line-wire to the insulator; to provide for rendering the work of attaching and detaching the line-wires ex tremely rapid; to prevent mutilating or kinking the line-wire; to provide for effectively securing or fastening the line-wire to the insulator; and to carry out the aforesaid ends in a simple and economic manner.

Said invention consists of certain features or instrumentalities substantially as hereinafter fully disclosed and specifically pointed out by the claims.

In the accompanying drawing illustrating the preferred embodiment of my invention Figure 1 is a front elevation thereof as applied to a cross-arm of a telephone'pole. Fig. 2 is a side elevation of the same devoid of pole cross-arm. Fig. 3 is a plan view of the parts as disclosed by Fig. 2.

In the disclosure of my invention, I employ an arcuate late-member 1 preferably of sheet metal an adapted to conform. and be applied to the ordinary insulator used upon telegraph poles or telephone line or other supports for the line-wire. Said member has its arms rovided with oppositely extending lateraI terminals 2 each provided with an elongated slot 3, the purpose of which will presently appear.

A clamp-member 4 preferably of stout wire and of practically U-form, is adapted to have its arms passed through the elongated slots 3 of the lateral terminals 2 of the platemember 1. Said clam -member has its arms extended to form ateral hooked terminals 5, which, however, are arranged at right-angles to the terminals 2 of the plate- ;member 1 and are adapted to receive or engage the line-wire and clamp it against said terminals 2 and thus provide for securing the line-wire firmly therebetween. A cam-lever 6, having its cam or eccentric portion presented toward, and adapted to bear upon the plate-member 1 about central of the convexity thereof, has pivotal connection with the clamp-member 4 close to its back edge.

It will be noted that, with thejdevicefisuitably applied to the insulator, as indicated in the several figures, the hooked terminals 5 are caught over the line-wire which is received in the annular groove of the insulator, and that, by then suitably actuating the cam-lever 6 the clamp-member 4 will be drawn upon so as to cause its said terminals to grip the line-wire and clamp it against the terminals 2 of the member 1, thus providing for clamping and securing said line-wire effectively in place upon the insulator.

It will be understood that the device remains as a fixture at all times upon the insulator, and that, in addition to possessing the advantages as above recited, by its use a great saving of time and labor in construction work is effected that firmness and effectiveness of grip are secured, and that repairs or alterations may be readily made. It is also noted that a further advantage of the use of this device is due to the fact that it is devoid of any large flat or projecting parts which would otherwise catch and retain snow, ice or water, and thereby become clogged.

The device, which may be designated generally as a clamp, it will be noted, comprises a plurality of members which are conformed to the insulator and are provided with means for gripping or engaging the line-wire and are so movable relatively to each other that they are caused to clamp both the line-wire and the insulator.

I claim 1. A line wire fastener comprising two clamps, the ends of one extending through the ends of the other and receiving the wire and a lever for forcing the clamps apart and creating pressure upon the wire.

2. A line wire fastener comprising two U- shaped clamp members, one having slots at its ends through which the ends of the other clamp extend, and one constructed at its ends to receive the line wire and a lever for applying pressure in to the clamps in opposite directions whereby the line wire is clamped and held fast between the four ends of the two clamps.

3. A device as described, comprising a plurality of clamp-members adapted for application to a line-wire insulator, one of said members being arcuate in outline and having lateral terminals provided with elongated slots, and the other clamp-member having its arms passed through said slots and provided with hook-ended terminals arranged at right angles to the terminals of the aforesaid member, said terminals being effective for gripping the line-wire, and a cam-lever having pivotal connection with the clamp-member having the hook-ended terminals.

4. A device as described, comprising an arcuate clamp-member having slotted outstanding or lateral terminals, an additional clamp-member having hook-ended terminals passed through said slotted lateral terminals, said terminals effective for clamping or gripping the line-wire between them, said clampmembers being adapted for application to a line-wire insulator, and a cam-lever having pivotal connection With said hook-ended clamp-member.

5. A device as described comprising two U-shaped clamps, one constructed and adapted at the ends to receive a line wire therethrough and the other to press against said line wire, and means pressing against said clamps to create this clamping pressure upon the wire.

In testimony whereof I afliX my signature, in presence of two witnesses.
